Concentration

Question 1

What happens if you increase concentration?

Answer 1

Equilibrium shifts to reduce concentration

Question 2

What happens if you decrease concentration?

Answer 2

Equilbrium shifts to increase concentration

Question 3

What happens if you increase H2 concentration (reactants) in
3H2 +N2-> 2NH3

Answer 3

Equilibrium will shift to the right to use it up and reduce concentration and more product 2NH3 will be produced

Question 4

What happens if you increase the 2NH3 (product) concentration?

Answer 4

equilibrium will shift to the left, to be used up and reduce concentration and more reactants (H2 and N2) will be produced.

Question 5

What happens if you increase the H+ concentration in

2CrO4 2- + 2H+ -> Cr2O7 2- + H2O-

Answer 5

Moves to the right and turns orange

Question 6

What happens if you decrease and add alkali

Answer 6

moves to the left and turns yellow

Question 7

When does concentration only affect a reaction

Answer 7

Only in Homogenous reactions- whereby reactants and products are in the same state
